Question

Obtenha, em cada caso, as coordenadas do ponto médio do segmento AB.
a) A(1, 7) e B(11, 3)
b) A(-6, 9) e B(-2, -5)
c) A(-3, 0) e B(9, 0)

Answer 1

Resposta:

$\dfrac{X_{1} + X_{2}}{2} = X_{m}$

$\dfrac{Y_{1} + Y_{2}}{2} = Y_{m}$

A) $(6, 5)$

$\dfrac{1 + 11}{2} = \dfrac{12}{2} = 6 = X_{A}$

$\dfrac{7+3}{2} = \dfrac{10}{2} = 5 = Y_{A}$

B) $(-4, 2)$

$\dfrac{-6 + -2}{2} = \dfrac{-8}{2} = -4 = X_{A}$

$\dfrac{9+-5}{2} = \dfrac{4}{2} = 2 = Y_{A}$

C) $(3, 0)$

$\dfrac{-3 + 9}{2} = \dfrac{6}{2} = 3 = X_{A}$

$\dfrac{0+0}{2} = 0 = Y_{A}$
